Resumen-Mejorar el rendimiento térmico de los edificios mediante la adaptación del aislamiento puede reducir la pérdida innecesaria de calor y energía minimizando el impacto ambiental. El aislamiento térmico interior es a menudo el elegido en los edificios históricos para preservar sus características. Sin embargo, el aislamiento interior puede aumentar la acumulación de humedad en paredes que socavan su durabilidad. Hay una falta de conocimiento sobre la eficacia de sólidos muros históricos y el impacto del aislamiento interno en su comportamiento higrotérmico. Este artículo investiga las propiedades térmicas e hídricas de siete opciones de aislamiento internos, incluyendo la pintura térmica, aerogel (AG), corcho-cal (CL), cal-cáñamo (HL), silicato de calcio bordo (CSB), tablero de fibra de madera (TFB) y placa de polisocianurato (PIR). Sus propiedades se comparan con un enlucido de cal tradicional. El PIR y el aerogel AG muestran extraordinarias propiedades térmicas que contribuyen a la comodidad y ahorro de energía, y la CL y HL son permeables al vapor y a la capilaridad. Estos tienen aproximadamente el doble de la masa térmica de los otros aislantes. Además, la CL tiene una buena inercia térmica (segunda difusividad más baja) y, a pesar de su contenido orgánico, una adsorción de baja a alta RH. Palabras

Internal thermal insulation is often favoured for historic buildings to preserve their features. However, internal insulation may increase moisture accumulation in walls undermining their durability. There is a lack of knowledge on the performance of historic solid walls and the impact of internal insulation in their hygrothermal behaviour. This paper investigates the thermal and hygric properties of seven internal insulation options including thermal paint, aerogel (AG), cork lime (CL), hemp lime (HL), calcium silicate board (CSB), timber fibre board (TFB) and polyisocyanurate (PIR) board. Their properties are compared with a traditional lime plaster. The PIR and aerogel AG show outstanding thermal properties that contribute towards indoor thermal comfort and energy savings and the CL and HL are vapour permeable and capillary active. They have approximately double the thermal mass of the other insulations. In addition, the CL has a good thermal inertia (2nd lowest diffusivity) and, in spite of its organic content, a low adsorption at high RH.

“…Experimental ones mainly compare TBCs with traditional coatings or other insulation systems, with the aim of reducing building energy needs or improving indoor thermal comfort [33][34][35][36][37]. Simulations focus on evaluating building energy savings or optimizing building envelope design to improve user comfort and decrease energy consumption [38][39][40][41][42][43][44][45][46].…”

“…• TBCs are often called "cool paints" in UHI papers and as reflective coatings even if some high emissive properties are mentioned; • Reflective paints are more efficient for avoiding solar energy absorption and reducing wall surface temperatures, with higher solar reflectances [33][34][35]45]; • Reflective paints can reduce inside air temperature in summer and increase it in winter, and so on, to be closer to the inside comfort temperature [35,[38][39][40][41][42][43][44] The TBC has to be placed outside the wall to be the most effective [38];…”

Adopting a multiscale approach is crucial for optimizing urban and building performance, prompting inquiries about the link between a technology’s local efficiency (building scale) and its broader impact (city-wide). To investigate this correlation and devise effective strategies for enhancing building and city energy performance, we experimentally examined a commercial nano-ceramic Thermal Barrier Coating (TBC) on a small-scale building and assessed numerically its influence on mitigating Urban Heat Islands (UHIs) at a city scale, translated in our case by the use of the thermal comfort index: the Universal Thermal Climate Index (UTCI). Our results reveal that the coating significantly curbs heat transfer locally, reducing surface temperatures by over 50 ∘C compared to traditional roofs and attenuating more than 70% of heat flux, potentially alleviating air conditioning demands and associated urban heat effects. However, implementing such coatings across a city does not notably advance overall efficiency and might trigger minor overheating on thermal perception. Hence, while nano-ceramic coatings indirectly aid UHI mitigation, they are not a standalone fix; instead, an integrated strategy involving efficient coatings, sustainable urban planning, and increased vegetation emerges as the optimal path toward creating enduringly sustainable, pleasant, and efficient urban environments to counter urban heat challenges effectively.
